The removeCue() method of the TextTrack interface removes a cue from the list of cues.
removeCue(cue)cueA TextTrackCue.
Undefined.
NotFoundError DOMExceptionThrown if the given cue is not found in the list of cues.
Note: The TextTrackCue interface is an abstract class used as the parent for other cue interfaces such as VTTCue. Therefore, when removing a cue you will be passing in one of the cue types that inherit from TextTrackCue.
In the following example a cue is added to a video text track using addCue(), then removed using removeCue.
let video = document.querySelector("video");
let track = video.addTextTrack("captions", "Captions", "en");
track.mode = "showing";
let cue = new VTTCue(0, 0.9, "Hildy!");
track.addCue(cue);
track.removeCue(cue);
